V Espanol To determine a target audience for a new software package, a computer company surveyed a large random sample of potential customers, asking each whether he/she uses a previous version of the software on a regular basis. (The company considered "a regular basis" to be at least three times a week.) The data, as summarized in the contingency table below, were classified according to two variables: the age of the respondent ("under 18", "18-35", "36-54", "55+") and software use ("on a regular basis" or "not on a regular basis"). Each cell of the table contains three numbers: the first number is the observed cell frequency (fo); the second number is the expected cell frequency (fg) under the assumption that there is no dependence between age and software use and the third number is the following value. ( 10 - (5 ) ? (Observed cell frequency - Expected cell frequency) fe Expected cell frequency The numbers labeled "Total" are totals for observed frequency. M Part 1 ( fo -(B ) Fill in the missing values in the contingency table. Round your expected frequencies to two or more decimal places, and round your values to fe three or more decimal places.
